Proceedings of the Fourth International Symposium on Fire Economics, Planning, and Policy: Climate Change and Wildfires Mega Wildfire in the World Biosphere Reserve (UNESCO), Torres del Paine National Park, Patagonia – Chile 2012: Work Experience In Extreme Behavior Conditions 1 in the Context of Global Warming René Cifuentes Medina2 Abstract Mega wildfires are critical, high-impact events that cause severe environmental, economic and social damage, resulting, in turn, in high-cost suppression operations and the need for mutual support, phased use of resources and the coordinated efforts of civilian government agencies, the armed forces, private companies and the international community. The mega forest fire that struck the Torres del Paine National Park and World Biosphere Reserve in the southern Magallanes region of Chile, in the period from December 2011 to February 2012, was caused by the negligent act of a tourist, in an area of difficult access by land and under extreme behavior conditions that made rapid access of ground attack resources even more difficult and made air attack impossible. Factors that influenced the event from the beginning were rapid rate of spread, high caloric intensity, resistance to control and long- distance emission of firebrands. On the other hand, the effects of climate change and global warming are being felt and viewed worldwide as a real threat, generating perfect scenarios for the occurrence of fires of this kind. Thus, this fire serves as a concrete example worthy of analysis for its magnitude, the considerable resources and means used, the level of complexity in attack operations, the great logistical deployments that had to be implemented due to the remoteness and inaccessibility of the site, the complications that had to be overcome, its impact on tourism and the local economy, the extensive media coverage it received, and its considerable political impact. Hence the need to draw from this experience those factors that could be taken into account in the prevention or suppression of highly-complex future fires, in order to help reduce the substantial environmental, economic, social and political effects generated by such fires. 1An abbreviated version of this paper was presented at the Fourth International Symposium on Fire Economics, Planning, and Policy: Climate Change and Wildfires; 5-11 November 2012, Mexico City, Mexico. 2Forestry Technician, Department Head, Fire Management, National Forest Corporation, Avenida Bulnes Nº 0333, Punta Arenas, Chile.

Fire as a disruptive agent at the regional level In Chile, and around the world, forest fires are a problem that leaves no one feeling indifferent. In our country, 99% of all wildfires are anthropogenic. Statistics also show us that on average 5,500 such incidents occur each year, burning some 52,000 hectares of vegetation, with losses of approximately $57 million US, corresponding to damages assessed on the market, such as wood, facilities, livestock and other assets, in addition to the social and environmental damage. Región de Magallanes y Antártica Chilena Chile Figure 1— Location of Chile History of fire in Torres del Paine Torres del Paine Park, located in the extreme south of Chile, has such outstanding natural features that it is one of the most popular tourist attractions in the country, both for Chileans and foreigners (about 80% of all visitors are foreigners). It is one of Chile’s most emblematic protected areas, as its approximately 242,000 hectares are home to a great variety of mountain scenery, glaciers and biological richness, which led to it being recognized as a World Biosphere Reserve by UNESCO, becoming the third most visited protected area in Chile (CONAF 2012). The increasing number of visitors to the Park (approx. 160,000 visitors annually) is having a negative effect on its natural resources, as manifested through different types of effects, among which 192 Proceedings of the Fourth International Symposium on Fire Economics, Planning, and Policy: Climate Change and Wildfires the one with the greatest impact is wildfires, which affect environmental quality and jeopardize the maintenance of the natural ecosystems and their sustainability. For its physical and biological landscape, it is also a major economic asset for the region, but at the same time it also poses a major threat, as the high rate of visitors implies an increased risk of occurrence of ignition sources (Vidal and Reif 2011). Thus, in the period 1980-2012, there were 61 recorded fires, all caused by humans, affecting more than 48,000 hectares of protected area, including the great fires of 1985 and 2005 (Vidal and Reif 2011) that preceded the fire of 2011. All the above reflects the uniqueness presented by the problem of forest fires in this region, since the environmental conditions, existing vegetation and a large number of mixed variables create conditions conducive to the spread of fire and which often make it difficult to combat them. In this way a small spot fire becomes a potential mega fire with disastrous consequences. The last major fire broke out in the Park in late December 2011, continuing for about a month in its most active phase and burning a total of 17,606 hectares, of which 17,054 are within the Park’s boundaries. Of the total area burned, an estimated 59.7% was Patagonian steppe communities dominated by grasses, 28.6% was scrub or shrubland, 9.7% was native forest and the remaining 1.9% was made up of other land uses. Named the Olguin mega fire after the area where it started, it is considered one of the most devastating wildfires to have ever occurred in the history of the Park as a protected area. The magnitude of the Olguin fire stands out not only for the vast area burned, but also for the severity of the fire, which affected the vegetation and soils, and because a large section of the burned area (50%) was also consumed by the great fire that hit the park in 1985 (USNPS 2012). As a result, the destructive impact is stronger and ecosystem resilience in these sectors is lower, meaning that fire recurrence is recognized as a factor leading to progressive degradation of ecosystems in the long term (Zarin and others 2005). Development of fire suppression operations The fire spread quickly due to constant strong winds, abundant and dry organic fuel present throughout the park, area conservation efforts and a prolonged drought, resulting in a high rate of spread, high resistance to control and long-distance emission of firebrands leading to multiple spot fires. The considerable resources and means required, the level of complexity involved in firefighting operations, the presence of extreme behavior factors, the great logistical deployments required due to the remoteness and inaccessibility of the site and the numerous complications that had to be solved, necessitated implementing 193 GENERAL TECHNICAL REPORT PSW-GTR-245 a complex extended attack structure, for which all material, technical and human elements in the Magallanes region were available through the local core civil protection system, the state civil protection system, and the mobilization of fire- fighting resources (CONAF and private fire crews) from central regions of the country under interregional mutual aid protocols, which were still insufficient. As a result, international cooperation was required and obtained by invoking mutual aid agreements and accepting offers of assistance from friendly countries. The fire was finally extinguished on February 23, 2012, although mopping up and ash monitoring operations continued until March 2012. Organization for complex extended attack (OOAAS) Since the resources arrived on a staggered basis, the organization mounted also grew on a pace with the arrival of fire personnel, so much so that by as early as January 3, the OOAAS could be completed, in terms of what was essential for handling the emergency, all of which caused further serious logistical problems due to the long distances involved and the complexity of the supply line.
